Cisco 400-007 Exam With Confidence Using Practice Dumps

The IS-IS Overload Bit allows a router to signal to its peers that it should be temporarily excluded from SPF calculations for transit traffic:

A: The Overload Bit can be automatically set at startup (known as "startup overload") to allow the router sufficient time to converge IGP, BGP, and stabilize protocols before accepting transit traffic.

D: The bit can remain set until all dependent protocols have converged and the router is fully operational.

Why other options are incorrect:

B: The router’s directly connected prefixes remain reachable; only transit path calculations exclude the overloaded node.

C: MPLS-TE does not automatically reoptimize tunnels based on the Overload Bit.

E: There is no specific restriction preventing Overload Bit usage on Route Reflectors.

To support high-bandwidth, low-latency Layer 2 communication between DB Server 1 and DB Server 2, you must create a direct Layer 2 path between SW1 and SW2. Using REP (Resilient Ethernet Protocol) segments ensures loop-free Layer 2 operation without the drawbacks of STP convergence delays.

Option C is correct: Adding a third REP segment (Segment 3) directly between SW1 and SW2 isolates the traffic between the two DB servers and ensures deterministic behavior with fast convergence.

Option A (LACP with STP) introduces STP blocking and doesn’t align well with REP's control plane.

Option B and D: Overloading existing segments or splitting new links into existing REP segments does not offer the same direct path, bandwidth, or deterministic behavior.

==========

Security design must be aligned with:

Business objectives (A): Security design must meet business needs without hindering operations.

Security policies and standards (B): Compliance with internal and external regulations is mandatory.

CCDE v3.1 teaches that security design always starts from business intent and policy compliance, not purely technical or scope-based factors.

Why other options are incorrect:

C & D: Security design applies to all environments, not just multi-site or new deployments.
